Nimy Resources Uncovers Deep Conductive Plates Hinting at Massive Copper-Nickel Potential
Nimy Resources has identified three key conductive plates near a major magnetic anomaly at its Masson discovery, suggesting a significant extension of copper-nickel mineralisation at depth within the Mons Project, WA.
- Three conductive plates detected by DHEM survey at Masson
- Mineralisation extends beyond previous drilling depths to at least 340m
- Conductive trend plunges toward a large magnetic anomaly, potential mineral source
- Masson target footprint expanded along strike and at depth
- Further assays and geological logging underway to confirm grades
Exploration Breakthrough at Masson
Nimy Resources (ASX – NIM) has announced a significant advancement in its exploration efforts at the Masson discovery within the Mons Project in Western Australia. A recent down-hole electromagnetic (DHEM) survey has revealed three conductive plates situated close to a major magnetic anomaly, providing compelling evidence of a substantial copper-nickel-PGE mineralised system extending well beyond previously drilled depths.
Extending the Known Mineralisation
The survey, conducted on drillhole NRRD165 which reached 444 metres depth, identified an upper conductive plate extending 240 metres with a very high conductance of 5,250 Siemens, and a lower plate extending a further 100 metres at 4,000 Siemens. These plates suggest mineralisation continues beyond the deepest intercepts recorded to date, which ranged from 91 to 288 metres. Notably, the upper plate indicates mineralisation extends to around 340 metres, with the lower plate pushing the conductive trend even deeper.
Vectoring Towards a Magnetic Anomaly
The conductive plates are plunging southwards towards a prominent magnetic anomaly identified through VOXI depth slice modelling at approximately 500 metres depth. This anomaly is interpreted as a potential source of the copper, nickel, and platinum group elements (PGE) mineralisation observed in shallower drilling. The dip and plunge of the lower plates suggest a levelling of the mineralised zone as it approaches this magnetic feature, reinforcing the prospect of a significant mineralised body at depth.
Implications for Mons Project Development
Managing Director Luke Hampson highlighted the importance of these results, noting that the combined evidence of known shallow mineralisation, the conductive plates, and the magnetic anomaly significantly enhances the high-grade potential of the Masson target. The discovery expands the footprint of copper-nickel-PGE mineralisation both at depth and along strike, with the system remaining open for further extensions.
Technical Geologist Dr John Simmonds is currently prioritising additional targets generated from a large-scale VTEM survey across the Mons Belt, indicating that Masson may be the first of several significant discoveries in this emerging district-scale project.
Next Steps and Ongoing Work
Samples from the upper 208 metres of hole NRRD165 have been submitted for assay, with diamond core undergoing detailed geological logging and initial XRF scanning. The company is planning follow-up soil sampling, further electromagnetic surveys, and additional RC and diamond drilling to test lateral and depth extensions of the mineralisation. These efforts aim to better define the resource potential and support future resource estimation.
With the Mons Belt spanning approximately 80 by 30 kilometres and hosting multiple prospective targets, Nimy Resources is positioning itself to unlock a new frontier of base metal and precious metal exploration in Western Australia’s Yilgarn Craton.
Bottom Line?
As assays and further drilling unfold, Masson’s growing mineralised footprint could redefine Nimy’s position in WA’s copper-nickel exploration landscape.
Questions in the middle?
- What grades will the pending assays from the deeper conductive plates confirm?
- How extensive is the magnetic anomaly at depth, and could it host a high-grade core?
- Which other VTEM targets in the Mons Belt might replicate Masson’s mineralisation style?
